Abstract (en)
[origin: EP2292926A1] Wind turbine blade with high-lift devices in the leading edge and/or trailing edge (the latter has a relative thickness) in the root area, so that aerodynamic performance is improved and therefore the amount of energy extracted from the wind compared to traditional blades with cylindrical or oval roots.
